[wp-hackers] Options table' varchar 64.

Large networks have a lot of options tables. For a sufficiently large table
(which might depend also on the storage engine), things could lock up or go
awry. Rather than just doing it once, we're doing it n times, where n is
the number of sites. More chances for things to go wrong.
My take is this:
If you are in a position to be able to run an ALTER TABLE query, you are
also probably hosting your own thing, which means you should stop storing
transients in the database. Instead, install an object cache. Transients in
the database are a last-resort kind of thing. If you're doing heavy stuff
with transients, look for alternatives.
Also, if your transient names are too long, use a prefix plus a hash of the
name. It'll make it constant-length.
